Sonovoltammetry at platinum electrodes: Surface phenomena and mass transport processes

Abstract:

Application of simultaneous ultrasound to representative solution-phase reversible voltammetric couples produce a step-shaped voltammogram at platinum electrodes of both 'macro' and 'micro' dimensions. The limiting current increases with ultrasonic power, but is not markedly affected by ultrasonic frequency in the 20-800kHz region. In contrast the complex voltammetry of a platinized platinum electrode surface within the hydrogen adsorption regime in aqueous acid medium is very little affected...
